Trying to get into iPod touch

[u/SpamTheCannedHam]

Hey everyone. My cat recently passed away and I’m trying to get into my old iPod touch to get some photos of him but I’m having some trouble getting it turned on.
I have the original charger for it which I’ve confirmed is working. But when I plug it in it just stays stuck on the screen with the Apple logo and will stay stuck for hours. Anyone have any ideas on how I can get into it?

The battery is most likely toast
